Apple used. AWACS was made by Crystal
Semiconductor. Bit clock is pin
42, sync is pin 43 and data in is pin 44. Headphone out L,R,Common
pins 27,25,28 Speaker out L,R,Common pins 29,31,30
Is that the 44 pin PLCC labeled CS4217-KL with the Crystal logo on
it? I was wondering about it--a datasheet didn't turn up, but I
easily found datasheets for the CS4216 and CS4218, whose pinouts seem
to be a country mile from the 4217.
